Huge Grain Cart Keeps Combines Moving
 ✖  |
Eric Johnson, Saskatoon, Sask., never liked sitting in his combine cab waiting for a truck or grain cart during harvest. Neither did his father, Harold. And in recent years they've had trouble finding anyone to drive their trucks for them.
The Johnsons grow 1,230 acres of peas, canola and wheat near Nokomis, Sask. Johnson also works in Saskatoon as an accountant. Harold is retired, except when Eric needs help in the field. To make harvest more efficient, Johnson designed the biggest grain cart FARM SHOW has ever seen. He got help engineering it from Tony Kaminski at the Saskatchewan Research Council and then hired Leon Ram, Yorkton, Sask., to build it in his metal shop, at a cost of about $85,000 (Canadian).
"It holds 5,000 bu., or about 25 dumps from the combines," he says. "It lets us both run combines for the better part of a day before we have to haul grain back to the farm."
The grain cart is 65 ft. long, 12 ft. high, and 14 ft. wide. It weighs in at 26,000 lbs. empty. Johnson says it's more of a portable bin than a cart, since it doesn't move once it's full of grain. Hydraulic cylinders raise the tandem axles up once the cart is in the field, so all the weight is on the frame rather than the tractor drawbar or the wheels.
A 9-in. auger that runs from back to front across the bottom of the bin empties into a 13-in. unloading auger in front that can be positioned to fill trucks on either side. Both augers run off the pto on a 4-WD tractor that pulls the cart to and from the field. At idle speed, it can load trucks at the rate of about 100 bu. a minute, so it takes only about five minutes to load a 500-bu. straight truck.
At the end of an average day, the Johnsons cover the cart with a roll tarp. Then they spend their mornings hauling grain, since crops are often too tough to combine then anyway.
If he were doing it again, Johnson says he'd first cut the load-out rate a little, since 100 bu. a minute can be too fast at times.
Secondly, he says he'd set the wheels inside the frame and a little farther forward. And he'd shorten the 12-ft. long hitch. "It doesn't corner as well as I'd like, but I think these changes would solve that problem," he says. Johnson says he knows other farmers might question the economics of making such a big cart. "I'm sure you could hire a truck driver with just the interest on the $85,000," he admits. "But it allows us to more fully use our own time. And if my father should ever decide to fully retire, I'll be able to harvest alone on my own schedule. It's getting so hard to hire help that I feel I need to be prepared for that. It'll also pay off in years when weather at harvest time isn't as good as it has been in recent years and I have only a few good days to get a crop out of the field."
